SPRING-WHIFFLETREE.

JPECIFICATIQN fermier part of Letters Patent No. 308,425, dated November25, 1884.

Application filed March 5, 1884. (No model.)

To all whom, it may concern:

Be it known that I, CYRUs B. Monsn, a citizen of the United States,residing in the city, county, and State of New York, have inventedcertain new and useful Improvements in Vhiffletrees, of which thefollowing is a specification.

My invention relates to that class of whiffletrees in which thedraft-strain is relieved or zo equalized by a spring connected to thecievis or draft-band and the whiffletree.

The object of my invention is to equalize the strain on each end of thespring, thereby preventing the breaking, weakening, or injuring of thespring by a sudden or unequal strain upon it when in use. I accomplishthis by making the spring and its support or seat free to oscillatearound its bearing. By the method at present in vogue the spring is made'20 a rigid fixture with the draft-band, whereby when the limit oftension in the spring is reached its elasticity is injured if the springitself does not break. My device allows the spring to have full play,renders its elasticity available to the utmost limit, and operates tocheck the tension or to control it, so as to prevent injury to thespring, aswell as to relieve the strain on the motive power.

In the application of my device the spring 3o and its support or seatmay be applied to whifiietrees, axle-trees, and similar structures, asheretoforem'ith this modification. rIhe spring and its support or seatis to be so connected that in its operation it will oscillate around 55the draft-bolt inside of the draft-band. It is not attached to thedraft-band, but is held in place by the draft-bolt, that passes throughthe draft-band and connects the whiffletree to the wagon, car, orstructure containing the load.

The draft-band has longitudinal slots through it to admit of a bolt orpin with a revolving sleeve on it operating within such slot. The

object of this pin is to keep the draft-band in a position central withthe whiffietree, and at the same time without preventing the draftbandhaving a free movement around the draftbolt, also permitting thewhiffletree to have a free sliding movement inside the draft-band.

I attain these objects by mechanism illus- 5o trated in the accompanyingdrawings, in

which- Figure l is a top view of oscillating spring and seat. Fig. 2 isa central cross-section of the same. Fig. 3 is a view of the spring-seatand draft-baud in position. Fig. 4 is a front 55 view of the saine. Fig.5 is a transverse crosssection through the line 5 5 of Fig. 3. Figs.

6 and 7 are elevations of the oscillating spring and seat in position onaxles of vehicles.

Similar letters refer to similar parts through- 6o out the severalviews.

The spring A is provided with a central bearing block or seat, B, thatis formed with a socket, b, in which the spring fit-s, and a recess, O,that receives the draftpin I). The 6 5 clevis or draft band I fits overthe middle of the whifiletree J, and is provided with a slot,

H, through which extends a headed bolt, G, carrying a friction -roller,G', whereby the hand is held in position on the whiffletree, and 7o isfree to have a transverse movementthereon. The draft-band is perforatedfor the draft-bolt D, which is shown in position in Fig. 5. The' springA extends through thedraft-band, and its seatispivoted on the draft-boltD. Swinging links E connect the ends of the spring to the whiffletree.Ihe whiffletree yis provided Qwith draft-clevises F, and is connectedwith the vehicle in the ordinary way.

In Figs. 6 and 7 the spring A is shown as 8o provided with clips B B2 L,that permit it to oscillate around the axle K.

I am aware that it has been proposed to constructa whiflietree withasliding draft-band, a spring centrally connected thereto, and swinginglinks to connect the ends of the spring to the whiffletree; but so faras I am aware aq spring has never before been pivotally connected to adraft-band, and such an organization affords material advantages; but 9cWhat I do claim as my invention,V and desire to secure by LettersPatent, is

l. The combination, substantially as set forth, of the whiffletree, thedraft-band, and the spring pivotally connected with the draftband, andhaving its ends connected with the whiffletree.

2. The combination, substantially as set` forth, of the whiffletree, thedraft-band, the spring pivotally connected with the draftroo band, andthe swinging links that connect the ends of the springs with thewhifdetree.

3. The combination, substantially'as set forth, of the whletree, thedraft-band that moves transversely on the Whiletree, the spring pivotedto the draft-band, and con- 5 neetons between the ends of the spring andthe whiletree.

4. The combination, substantially as set forth, of the draft-bolt, thespring, and the seat formed with a socket in which the spring issecured, and a ree'essed bearing by which 1o the seat is pivot-allyconnected with the draftv bolt. Y
